A ceremony and a series of events were held here to mark the centennial of the Work-Study Movement. Starting in 1919, thousands of progressive young Chinese went to France, where they worked in factories in Paris, Lyon and Montargis to pay for their studies in the European country. Some of them became interested in Marxism and established one of the earliest Chinese communist party groups in France. (Xinhua/Shan Yuqi)
